Synchronous control mechanism for radial resetting of taper pin

Abstract

The utility model discloses a taper pin radial reset synchronous control mechanism, a handle in a handle shell is connected with a supporting piece through a spring, and a sliding block is connected with the supporting piece. The steel cable penetrates through the handle shell to be connected with the sliding block. The other section of the steel cable is connected with a long spring, and the bottom end of the long spring is connected with the tail of the conical surface sliding pin. When the handle is located at the manual locking position, the conical surface sliding pin connected with the steel cable in the flexible shaft slides forwards under the action of the spring to jack the lifting pin of the locking mechanism of the crimper, so that the function of locking the shoulder strap is achieved. When the handle is in the automatic locking position, the conical surface sliding pin is pulled back to the original position by the steel rope, and the non-locking state of the curling device is recovered. The safety belt shoulder belt locking mechanism can quickly and conveniently lock the safety belt shoulder belt, can quickly release the safety belt shoulder belt when leaving, and is safe and reliable.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of aircraft safety belt, concretely is a kind of taper pin radial reset synchronous control mechanism. BACKGROUND

[0002] In the previous aircraft safety belt product, domestic pilot safety belt is basically without taper pin radial reset synchronous control mechanism, which leads to that pilot cannot manually adjust the webbing movement in the retractor inside in aircraft safety belt product on seat, leads to that pilot's body is locked on seat after wearing safety belt, and the activity space is less.Due to some reasons, when the driver makes a large range of activity to upper torso, cannot quickly move forward and backward on seat, and experience and comfort are relatively poor.Therefore, customer hopes to configure a kind of taper pin radial reset synchronous control mechanism, can be operated by pilot this mechanism, and whether the webbing inside retractor needs to be locked is decided autonomously. SUMMARY

[0003] The utility model aims at providing a kind of taper pin radial reset synchronous control mechanism, it can quickly lock safety belt retractor, so that shoulder strap cannot be stretched out.

[0004] The technical solution for achieving the utility model aims at providing a kind of taper pin radial reset synchronous control mechanism, it can quickly lock safety belt retractor, so that shoulder strap cannot be stretched out.

[0005] The handle in the handle shell is connected with support piece by spring, and the sliding block is connected with support piece;Steel cable passes through the handle shell and is connected with sliding block;Long spring is connected at the other end of steel cable, and the bottom end of long spring is connected with the tail of taper pin sliding block.

[0006] Further, the long spring and taper pin sliding block are protected by joint shell.

[0007] Further, the support piece controls the sliding block to move forward and backward by spring, so that steel cable in sliding block can push taper pin sliding block, to control the movement of webbing in retractor.

[0008] Compared with prior art, the device of the utility model is connected with the retractor assembly of safety belt, and after adding taper pin radial reset synchronous control mechanism, becomes a component in aircraft pilot safety belt product.Pilot controls the movement of webbing in retractor inside by taper pin radial reset synchronous control mechanism, automatic locking function and manual locking function, not only can effectively restrict upper torso and head and neck, so that it is not hurt, simultaneously, the activity space of driver on seat is greatly increased, and the comfort of pilot driving aircraft is improved. BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 It is the structure schematic diagram of the utility model. DETAILED DESCRIPTION

[0010] The conical pin radial reset synchronous control mechanism is a component in a pilot safety belt product.

[0011] The details and working conditions of the specific device according to the utility model will be described in detail below. Figure 1 DETAILED DESCRIPTION

[0012] The conical pin radial reset synchronous control mechanism is as shown in Figure 1 It mainly comprises a handle shell 1, a spring 2, a sliding block 3, a handle 4, a steel cable 5, an elongated spring 6 and a conical sliding pin 7. The handle shell 1 is connected with a support sheet through the spring 2, and the sliding block 3 is connected with the support sheet. The steel cable 5 is connected with the sliding block 3 through the handle shell 1. The other end of the steel cable 5 is connected with the elongated spring 6, and the bottom end of the elongated spring 6 is connected with the tail of the conical sliding pin 7. The support sheet controls the sliding block 3 to move forward and backward through the spring 2, so that the steel cable 5 in the sliding block 3 can push the conical sliding pin 7, thereby controlling the movement of the belt in the retractor.

[0013] When the handle 4 is in the "manual locking" position, the conical sliding pin 7 connected with the steel cable 5 in the soft shaft slides forward under the action of the elongated spring 6, pushes the top pin 8 of the retractor locking mechanism, moves the leaf spring 9 to prevent the inertial plate 10 and the shaft 11 from moving synchronously to lock the telescopic belt 12. When the handle is in the "automatic locking" position, the conical sliding pin 7 will be pulled back to the original position by the steel cable 5, and the top pin 8 will also drive the leaf spring 9 to move away from the inertial plate 10 under the action of the elongated spring 6, thereby restoring the non-locking state of the retractor.

[0014] The utility model can quickly and conveniently lock the safety belt shoulder belt, and can be quickly released when leaving, which is safe and reliable.
